  1. Measure OD of Pipe and select seal from above ensuring tolerances are met. Use the Part No. above as ordering code.
  2. Using the appropriate size holesaw, cut a hole to the correct
    size for the Uniseal you are installing. Ensuring that the hole is a clean cut as irregularities could result in a poor seating and leakage.
    Eg. A 2” Uniseal needs a 3” Hole saw
  3. Place the Uniseal into the hole with the wide side facing the direction the pipe is going to be inserted.
  4. Ensure that the pipe end to be inserted is clean cut. Chamfer/bevel the edge of the pipe so that there are no sharp points to cut the Uniseal.
  5. Using liquid soap or detergent, lubricate the outside of the pipe to be inserted, then push the pipe through the Uniseal from it’s wide side. The detergent will be squeezed off as the pipe passes through the Uniseal. The coefficient of friction of rubber holds the pipe tightly in place.uniseal
